hmm...looks like its about that time, The best way to know its done is by checking the trichomes, you need a jewelry microscope, I believe you can get a high powered microscope from Radio shack. If your looking for an uppy high like a sativa I believe you would like the trich's to be mostly cloudy, IM DEFINATELY NOT A PROFESIONAL. The grow FAQ page can help you with this. In my eyes It should be ready for cutting.
